Cylindrical fenders may look simple, but their performance relies on more than geometry alone. Rubber formulation and manufacturing processes have a significant influence on elasticity, durability and long-term shape retention.

During years of outdoor exposure and repeated contact with vessels, rubber fenders can experience flattening or deformation. If the material cannot recover effectively after impact, its protective performance may be affected.

For this reason, formulation technology is an important part of marine rubber fender manufacturing. The right material properties help maintain consistent performance through repeated use.

At SME Marine, quality control covers each stage of production, including raw material selection, manufacturing and final inspection. We continue to improve cylindrical marine fenders through formulation development and process control, with a focus on safety, durability and extended service life.
